DEVICE FOR SPINNING GLASS.

Specification of Letters Patent.

Application filed April 14, 1909. Serial No. 489,779.

To all whom it may concern:

Be it known that I, IVAN Wursnorr, cloctor of medicine, manufacturer, asub ect of the Emperor of Austria-Hungary, anda resident ofMorchenstern, Bohemia, in the Empire of Austria-Hungary, have invented 0Glass; and I do here-,

a Device for Spinnin by'declare the followlng and exact description 0 tobe a full, clear, the invention, such as will enable others skilled inthe art to which it appertainsto make and use the same.

The subject-matter of the present invention is a device for spinningglass for the purpose of producing so-called glass wool; or glassthreads or filaments for optional:

purposes, but particularly for insulating purposes.

open in front and ex osed to the flame,

toward which the rod 0 glass is fed forward 5 automatically inproportion to the diminui tion of the melted glass mass which is drawn 1away in filamentary form.

In order that the inventionmay be clearly understood reference will bemade to ,the' accompanying drawing in which one con-' structional formof such a device is reprefi- 'sented by way of example, and in -whic h:j

Figure l is a longitudinal section through 1 the device, andFig. 2' isan end elevation partly in section of the same, whereas Fig. 3 showspart of the device as shown in Fig.

1 on a larger scale, and Figs. 4 and 5 are details in sectionalelevation .explainedheref after.

Similar reference characters denote like parts in all views.

2, 3 adjustable in height are arranged which serve for supporting anumber of chutes 1 arranged beside one another, ineach of: which one ormore thin glass rods flare placed. The rear stands 3' have verticallygadjustable hooked extensible members .6 and .the front stands 2 a plate7 provided with suitable incisionsforthe-chutes and wise adjustablevertically. In front of the stands 2 is arranged beside one another anumber of supports or stands 8'which carry Patented Jan. 11, 1910.

the hollow body or fusing point 9. The

fusing point is, generally speaking, a fireproof hollow body open infront and at the rear,'into which the end of the glass rod enters up toa stop or shoulder in the hollow body. According to the formrepresented,

the hollow 'body 9 has the shape .of a cylinder which is rovided at itsrear end with or more laterally arranged holes 11. \Vhen one hole onlyis provided, itmay be located exactly in the axis of the body and be ofoptional shape, for example that of a slot or small round hole.

small hole 11 at the point and laterally in the conical end of thefusing point 9, The fusing point itself is attached to the support 8 bya covering member 12 provided with a hole through it and firmly screwedto the support. The flame, which has heretofore acted directly on theend of the glass rod, is now directed against the fusing point. For thisa burner tube 1-3 is used which, like a Bunsen burner, receives airflanges '10 an possesses at its front end one Figs. 4 and 5 respec-.tively clearly show the arrangement of a The improved device accordingto the invention differs from the known device fori spinning glass,which consists in the end of a glass rod being exposed to an open jet offlame produced at the blowing table, by the rod of glass resting withits end in a fire proof hollow body, a so-called fusing point, I

from the pipe 1 1 and gas from the pipe 1 5.

1 In order to obtain an intense heat .at. that place at which the glassfilament of thread 1s drawn away. from the fused lass, z'. e. at thehole 11, a blowpige flame is directed against this place by m'ansbf theburner k 16; the latter is fed with gals-and air from the pipes 141 and15, as clearly shown. As

the present arrangement readily enables a number of fusing devices to beplaced beside one another, several fusing points 9 are provided; besideone another, in eachof which .a glass i'od, guided in a chute, enterswith its end, and againstwhich the flames of the two burner tubes '13,,16 act. It is to be j noted tihat the pipes'l, 15 open into com.-

Referring to the drawing, the device consists of a table 1, onwhichstands or pillars box 01 Casing 21 provided which incloses place.When a drop of glass is visible, the

operator touches itwith a small rod having a glass point directedthroughthe opening 23 of the box 21, withdraws the same quickly, and throws itin the manner usual heretofore onto a rapidly rotating drum on which theglass filament is wound up.

The advantages of the described means 'are manifold. They consist in thepossibiltemperature can be gradually increased up to the melting pointof the glass, and dropping of }he glass and breaking of the filament orthread caused thereby are prevented.

It may be mentioned that the glass spinningprocess can be carried intopractice not only together With the two flames 13, 16,

but also with the one or other flame alone, without departing from thespirit and scope of the invention.

What I claim as my invention and desire to secure by Letters Patent is:

1; In a device for use when spinning glass, the combination of a table,a refractory hollow body or fusing point open at the rear and in frontand carried on said table, a burner on said table for heating said body,and means for automatically feeding'a glass rod into said body inproportion'as fused glass is removed therefrom, substantially asdescribed. v v

2. In a device for use when spinning glass, the combination, with atable, of a chute mounted adjustably thereon, a refractory hollow bodyor fusing point open in front and at the rearmounted on said table infront of and in line with said chute, and a burner attached to saidtable for heating said body, substantially as described.

3. In a device for use when spinning glass, the combination, with atable, of a chute mountedadjustably and slanting thereon, a refractoryhollow body or fusing point open in front and at the rear mountedslantwise on said table in'front of and in line with said chute, and aburner attached to said seams table for sending a flame through theopening in the front of said body, substantially as described.

4:. In a device for use when spinning glass, the combination, with atable, of a chute mounted adjustably thereon, a refractory hollow bodyor fusing point open in front and at the rear mounted on said table infront of and in line with said chute, a burner attached to said tablefor heating said body, and another burner attached to said table forsending a flame through the opening in the front of said body,substantially as described.

5. In a device for use when spinning glass, I

the combination, with a table, of a chute mounted adjustably andslanting thereon, a

refractory cylindrical flanged hollow body or fusing point open at therear and having a lateral hole at its front end, said body beingsupported by means of the flange slantwise on said table in front of andin line with said chute, and a burner attached'to saidtable for heatingsaid body, substan-,

slantwise on said table in front of and in line with said chute, aburner attached to said table for heating said body, and a guardarranged on the table at the front end of the hollow body, substantiallyas described.
